Specification of Letters Patent.

Patented May 11, 1915.

Application filed December 10, 1912. Serial No. 735,882.

To all whom it may concern Be it known that I, THOMAS H. SIMPSON, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Car- Couplers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to car couplers of the J anney type, and consists in the novel construction of means for operating the locking detent and knuckle-opening mechanism as hereinafter set forth.

In the drawings: Figure 1 is a side elevation of the coupling. Fig. 2 is an end elevation thereof.

A is the body of the coupler: B the hinged knuckle or coupling hook; and O the detent which engages with the actuating arm of the coupler to hold thesame incoupled position. This detent is operated from below, and is provided with a downwardlyextending shank D, which is engaged by a bell-crank lever E fulcrumed at F, and having its actuating arm extending upward adjacent to the side of the coupler body.

It is the primary object of the invention to obtain a construction in which the detent actuating-mechanism is almost completely housed in the body of the coupler, and one which also increases the strength of the structure. This I have accomplished by providing a downward extension G of the coupler body to form a housing for the horizontally-extending arm E of the lever E. The end of this downward extension is formed with an open slot for the entrance and movement of the lever, which above this point the body of the coupler is provided with laterally-extending flanges H embrac- G'opies of this patent may be obtained for five cents each, by addressing the ing the upwardly-extending arm E of the lever and forming a bearing for the fulcrum pin F. Thus in the normal position of the lever, the actuating arm E is protected by the flanges H, while the actuating arm E is housed between the parallel flanges of the downward extension protected thereby. The body of the coupler is sufficiently cut away to provide clearance for the movement of the lever, but this does not weaken the structure, as the downward extension G has an integral bottom, and furthermore, a second strengthening wall I is formed in the body above the path of movement of the lever.

The coupler constructed as described, may be located within a smaller space than constructions heretofore employed and may be operated by merely attaching a straight pull rod to the upper end of the lever E. Furthermore, as all the mechanism is housed, there is less danger of injury to the same.

What I claim as my invention is:

In a car coupler, the combination with a body and swinging knuckle, of a detent for locking said knuckle vertically adjustable within said body, a downwardly extending shank on said detent, a bell crank lever fulcrumed at the side of said body having an arm extending inward into engagement with said shank, and a downward extension of said body having parallel walls embracing the inwardly extending portion of said lever with connecting walls above and beneath said lever.

In testimony whereof I afi'ix my signature in presence of two witnesses.

THOMAS H. SIMPSON.
